Why is Zn but not copper used for the recovery of Ag from its cyanide complex `[Ag(CN)_(2)]^(-)`

Why is zinc and not copper used for the recovery of metallic silver from its cyanide complex [Ag(CN)_(2)]^(-) ?

Explain the following : Why is zinc and not copper used for the recovery of silver from the complex [Ag(CN_2)]^- ?

Explain the following (a) Although Au is soluble in aqua-regia, Ag is not (b) Zinc and hot copper is used for recovery of Ag from the complex [Ag(CN)_(2)]^(-) (c) Aluminium metal is frequently used as a reducing agent for extraction of metal such as chromium manganese etc. (d) Partial roasting of sulphide ore is done in the metallurgy of copper.

STATEMENT-1 : Zinc and not copper is used in the recovery of silver from the complex [Ag(CN)_(2)]^(-) and STATEMENT-2 : Zinc is more powerful oxidising agent than copper.
